Whilst this is not a default behavior in EA, and some EA practitioners even argue against such a request.
I've seen one of my client in a similar situation, where there was a need to traverse from a business process to use cases without adding the requirements on to the picture (Their usual hierarchy business process -> Requirements -> UCs) We ended up automating trace connectors creation in this particular instance. Where everytime a requirement is linked to a usecase, and if the same requirement is linked to a business process, a trace relationship is created between UC & BP.
NB - This could end up in really messy relationships, if you don't constraint it for specific purpose
